How can I order by key as integer?

I have the following Object;

 $scope.data = {
    \"0\": { data: \"ZERO\" },
    \"1\": { data: \"ONE\" },
    \"2

    An option would be use an intermediate filter.

    PLUNK AND Code Snippet

    var app = angular.module('app', []);

app.controller('MainCtrl', function($scope) {
  
  $scope.template = {
    "0": { data: "ZERO" },
    "1": { data: "ONE" },
    "2": { data: "TWO"  },
    "3": { data: "TREE" },
    "5": { data: "FIVE" },
    "6": { data: "SIX" },
    "10":{ data:  "TEN" },
    "11": { data: "ELEVEN" },
    "12": { data: "TWELVE" },
    "13": { data: "THIRTEEN" },
    "20": { data: "TWENTY"}
  }
 
});

app.filter('toArray', function() { return function(obj) {
    if (!(obj instanceof Object)) return obj;
    return _.map(obj, function(val, key) {
        return Object.defineProperty(val, '$key', {__proto__: null, value: key});
    });
}});
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.7.0/underscore.js"></script>

<body ng-app="app" ng-controller="MainCtrl">
    <div ng-repeat="(key, value) in template| toArray | orderBy:key">{{key}} : {{value.$key}} : {{value.data}}</div>
<body>

    NOTE:

    The above filter requires Underscore.js, if you don't use it, can rewrite the filter.

    app.filter('orderObjectBy', [function()  {
  return (filterObj, prop) => {

    let arr = []
   //below is the loadash function you can use for in also
   _.forEach(filterObj, function(value, key)  {
   arr.push({
   key: key,
    value: value
     });
  });

let sortedArr = _.sortBy(arr, val => val.value[prop]);

  for (let variableKey in filterObj) {
 if (filterObj.hasOwnProperty(variableKey)) {
  delete filterObj[variableKey];
    }
   }

  for (let data of sortedArr) {
 filterObj[data.key] = data.value;
 }


  return filterObj;

   }
 }])

    I think it sorts itself out with a conversion to an array. pun intended.

    var obj = {"3": {three:3}, 2: {two:2}, "5": {five:5}, 4: {four:4}, 
  1: {one:1}, 6: {six:6}, 10: {ten:10}, 11:{eleven:11} 
} 

$scope.arr = [];

for (var o in obj)
   $scope.arr.push(obj[o])
